A pediatric patient, who was given live-attenuated oral polio vaccine twice without distinct gait disturbance during infancy, begun to present limp at 3 years. His gait disturbance became remarkable with aging. At 7 years, he was unable to dorsiflex the left ankle, and presented flaccid monoplegia of the left lower extremity, and the left Achilles tendon reflex was diminished. Magnetic resonance imaging revealed multiple crack-lines in the left anterior tibial muscle, but was unable to detect any distinct lesion at responsible level of L4, L5 and S1 anterior horn cells' degeneration. Electromyography showed continuous fibrillation potentials, but muscle biopsy presented nearly normal in this muscle. The serum levels of polio antibody type 1 and type 2 titers were elevated 64× respectively, while the type 3 antibody titer was not elevated 4×. This patient was diagnosed as live attenuated oral polio vaccine-related flaccid monoplegia, with mild clinical course.

Background/objectives: Conventional live oral poliovirus vaccines (OPVs) effectively prevent poliomyelitis. These vaccines are derived from three attenuated Sabin strains of poliovirus, which can revert within the first week of replication to a neurovirulent phenotype, leading to sporadic cases of vaccine-associated paralytic poliomyelitis (VAPP) among vaccinees and their contacts. A novel OPV2 vaccine (nOPV2) with enhanced genetic stability was developed recently; type 1 and type 3 nOPV strains were engineered using the nOPV2 genome as a backbone by replacing the capsid precursor polyprotein (P1) with that of Sabin strains type 1 and type 3, respectively.

In 2024, circulating vaccine-derived poliovirus type 2 (cVDPV2) was detected in wastewater samples in Finland, Germany, Poland, Spain and the United Kingdom (UK). All strains were genetically linked, but sequence analysis showed high genetic diversity among the strains identified within individual wastewater sites and countries and an unexpected high genetic proximity among isolates from different countries. Taken together these results, with sequential samples having tested positive in various sites, a broader geographic distribution beyond positive sampling sites must be considered.

Introduction: Health camps are organized to provide basic health services in underprivileged communities. This study was conducted to determine community acceptance and effectiveness of health camps in the high-risk areas for the polio program in Karachi, Pakistan.
Methods: This cross-sectional survey was conducted at the health campsites in high-risk union councils (HRUCs) of four districts of Karachi, Sindh.
Synergistic combination of orally available safe-in-man pleconaril, AG7404, and mindeudesivir inhibits enterovirus infections in human cell and organoid cultures.

Enteroviruses can infect various human organs, causing diseases such as meningitis, the common cold, hand-foot-and-mouth disease, myocarditis, pancreatitis, hepatitis, poliomyelitis, sepsis, and type 1 diabetes. Currently, there are no approved treatments for enterovirus infections. In this study, we identified a synergistic combination of orally available, safe-in-man pleconaril, AG7404, and mindeudesivir, that at non-toxic concentrations effectively inhibited enterovirus replication in human cell and organoid cultures.
